Embodiment Construction

[0015] Such as figure 1 Shown is an environment architecture diagram of a preferred embodiment of the system for improving the input accuracy of a capacitive touch screen according to the present invention. The system 10 for improving the input accuracy of a capacitive touch screen (hereinafter referred to as “enhancing system 10 ”) runs on an electronic device 1 , and the electronic device 1 includes a capacitive touch screen 12 and a controller 14 .

[0016] The capacitive touch screen 12 works by utilizing the current induction of the human body. When a finger touches the touch screen, due to the electric field of the human body, the user and the surface of the touch screen form a coupling capacitance. For high-frequency currents, the capacitance is a direct conductor, so the finger absorbs a small current from the contact point. This current flows out from the electrodes on the four corners of the touch screen respectively, and the current flowing through these four elect...

Abstract

The invention discloses a method for improving the input accuracy of a capacitive touch screen. The method comprises the following steps of: decreasing the size of a sensing area of each key of a virtual keyboard; acquiring the position information of a touch point from a controller; acquiring a triggered key instruction according to the position information of the touch point; increasing the size of the sensing area of the key which is touched currently; and sending the triggered key instruction before a finger leaves the capacitive touch screen to an electronic device for processing, when receiving an instruction indicating that the finger leaves the capacitive touch screen. The invention also provides a system for improving the input accuracy of the capacitive touch screen. By the invention, the input accuracy and effectiveness of a user in the electronic device applying the capacitive touch screen can be improved.

Description

technical field [0001] The invention relates to a system and a method for improving input accuracy, in particular to a system and method for improving the input accuracy of a capacitive touch screen. Background technique [0002] At present, more and more people favor touch-screen mobile phones with convenient operation, among which capacitive touch screen is one of them. Capacitive touch requires a minimum area to locate the position. And strength, accurately calculate the position of the touch point. [0003] However, when the virtual keyboard on the capacitive touch screen is used for input, since people's fingers are generally larger than the virtual keyboard on the touch screen, when touching the keys on the virtual keyboard, more than one key is often touched or covered. At the same time, when the button to be selected is always covered, the user does not know which button will be triggered. Therefore, it is easy to cause low input accuracy and reduce input speed. ...
